Methods for chaining together two or more navigation or survey stations to complete a project, where only adjacent stations in the chain have contact with each other. The location of a mobile reference station is determined and corrected, if necessary, using location determination (LD) signals from an LD system such as GPS, GLONASS, LEO or the like. The location of a first rover station is determined using RTK information and signal differencing from the mobile reference station. The location of a second rover station is determined using RTK information and signal differencing from the first rover station, in a chain of location determinations. Standard electronic distance measuring equipment and techniques can be used to supplement these methods in an integrated approach. Location consistency checks are provided by using RTK analysis to redetermine the location of one or more preceding stations in the chain. The invention can be used to direct a moving vehicle toward a selected structure for landing, tie-up, maintenance, refueling and similar activities.

[ What is claimed is:] [1.] A method for determining location of a rover station, the method comprising the steps of:providing information on a known location for a base reference station and real time kinematic (RTK) information on base station location for a mobile reference station that is spaced apart from the base station;using the base station RTK information to determine a location of the mobile reference station relative to the base station location;providing the mobile reference station location and RTK information concerning the mobile reference station for a first rover station that is spaced apart from the mobile reference station;using the mobile reference station location information and RTK information to determine the first rover station location relative to the mobile reference station location;using the first rover station location and the RTK information concerning the first rover station to redetermine the mobile reference station location;comparing the redetermined mobile reference station location with the location of the mobile reference station, as originally determined; andwhen the redetermined mobile reference station location does not substantially agree with the originally determined mobile reference station location, determining that the originally determined location of at least one of the mobile reference station and the first rover station is erroneous.
